You’ve been putting $200 a month into an Emergency fund envelope for a year. The envelope reads $2,400, which is the point. But your budget’s Available to spend also reads $2,400 higher than it should, which is not. Every rollover envelope has this problem: the balance that makes it a savings envelope is the same balance your budget treats as spendable. We built Reserved categories to fix that. Mark the envelope as reserved and its surplus leaves the headline number, while the envelope itself keeps showing exactly what you’ve saved.
Here’s what changed, what didn’t, and when to use it.
The problem with a savings envelope
The envelope system is cash budgeting at its simplest: put this month’s grocery money in one envelope, gas money in another, and when an envelope is empty you stop spending from it. Skwad’s rollover categories bring the same idea to your accounts. A rollover envelope carries its leftover balance into the next period, which is exactly what you want for saving toward something.
The catch is what “leftover” means to the rest of your budget. Every dollar of under-budget surplus, across every envelope, rolls up into Available to spend. For a Dining envelope with $40 left, that’s correct. You could spend it. For an Emergency fund with $2,400 in it, it’s wrong. You could technically spend it, but the whole reason it exists is that you won’t. So the number you glance at to decide whether you can afford the thing in your cart has been quietly inflated by the money you’ve promised not to touch.
What Reserved does, and what it leaves alone
We changed exactly one thing. A reserved category’s surplus stops counting toward your Available to spend. That’s it.
Everything else stays put. The envelope’s own row still shows exactly what’s in it, so you can watch the fund grow. Nothing moves between categories, nothing resets, and turning Reserved off puts the surplus back into the total immediately. It’s a display-and-math setting, not a transfer.
Overspending still counts. If a reserved category goes negative, it reduces your Available to spend by the full shortfall, the same as any other category. Reserved can hide savings from the headline. It can’t hide a hole.
Where you’ll see it
On the category row, a small lock sits next to the available value. The value itself doesn’t change; the lock just marks the envelope as set aside. In the Spend summary, a Reserved line appears in the running total as a deduction, so Available to spend drops to the spendable figure and the math still balances when you read down the column.
Parent categories show the lock only when every child under them is reserved. A mix of reserved and normal children leaves the parent unlocked. And the Plan tab is unaffected, because assigning funds is about allocating money rather than spending it, so it still counts every envelope. The iOS widget’s available number respects Reserved too.
When to reserve a category
Reserve the envelopes you’re building, not the ones you’re spending:
- An emergency fund, a balance you want to grow and leave alone
- Sinking funds, where you save toward a known future expense like car maintenance, annual insurance, or the holidays
- Long-term savings goals you keep inside your budget rather than in a separate account
Keep everyday spending categories un-reserved so their surplus shows up as available. If you’re using something like the 50/30/20 split, Reserved is how your 20% stops leaking into the 30%.
Budgets created from our starter template now reserve Transfer to Savings from the start, so new Skwads get this behavior without touching a setting.
How to turn it on
Open your budget, pick a category, and open its options. On a rollover category you’ll see a Reserved toggle. Flip it, and the lock appears on the row and the Reserved line appears in your Spend summary. On a basic category the toggle shows grayed out with a note, because a category that resets each period has no balance to protect. Switch it to rollover first if you want to reserve it. The reserved categories guide has the details. New to how balances carry between months? Start with adjusting a budget without changing history.
Frequently asked questions
Does turning on Reserved move any money? No. Reserved is a display-and-math setting. Turn it off and the surplus counts toward Available to spend again immediately.
What happens if I overspend a reserved category? It counts. A reserved category that goes negative reduces your Available to spend by the full shortfall, the same as any other category. Reserved hides savings from the total; it never hides an overspend.
Why can’t I reserve one of my categories? Reserved only applies to rollover categories, because a basic category resets each period and has no balance to protect. Switch the category to rollover first and the toggle becomes available.
Does Reserved change the Plan tab? No. Assign funds is about allocating money, not spending it, so the Plan tab still counts every envelope.
Reserve your emergency fund tonight and look at Available to spend tomorrow morning. That smaller number is the one you can actually trust.
